ENGRAVINGS. 
PLATE 22. 
All illustrations on this plate are one and a fourth times natural size. 
Figs. 1-2: Engravings on a proboscidian tusk from the Pleis¬ 
tocene of Florida. The tusk on which these markings are found 
is probably a lower tusk of Manumit americanum. That it is a 
proboscidian tusk is clearly evident by the characteristic structure. 
The specimen was found near the base of the stratum No. 2 on 
the north bank of the canal 370 feet west of the bridge and was 
taken from the bank in the presence of the writer by Isaac M. 
Weills. The section of the canal bank at this place and also a list 
of the associated fossils is given in the text. Actual length of 
tusk 133 mm. Fla. Surv. coll. No. 6789. (Field No. ioi.)_p. 134 
Fig. 3 : Fragment of bird bone showing markings. Same lo¬ 
cality as the tusk. Fla. Surv. coll. 6783. The bird represented is 
probably Jabiru? zveiUsi. sp. nov., the type specimen of which was 
found at the same place in the bank. 
The section of the canal bank at the place where these speci¬ 
mens were found is shown in text-figure 4.
